Application filed October 10. 1964. Serial No. 227.900.

To all whom it may concern:

Be it known that I, VICTOR )HAIN, a subject of the King of GreatBritain, residing at "7 AvonmoreGardens, West Kensington, in

of inclosing the sweetmeat in ordinary tin foil covering or othersuitable wrapping,

and shaping, moldingand cooling the sweetmeat by mechanical meanswithout contact with the hands of the operatives.

An essential feature of the invention consists inmolding and wrappingthe sweetmeat in its plastic state and effecting the cooling While thejsWeetmeat-is confined in the wrapping-and in the mold.

In order that the said invention may be clearly understood and readilycarried into eliect we will proceed to describe the same with referenceto the accompanying drawings which illustrate by way of example, a ma-'chine adapted for accomplishing the objects in view.

Figure l is a view artly in elevation and partly in longitudinal sectionof a machine whereby the sweetmeat may be molded, wrapped and cooledwithout being subjected to handling by the operatives. Fig. 2 is ahorizontal section taken along the line 22 in .Fig. 1. Fig. 3 is. atransverse section taken along the line 3-3 in Fig. 1. Fig. 4 is atransverse section'taken along the line 44 in Fig. 1. Fig. 5 is afragmental sectional view of the mouth piece; Fig.-6 is a sectional viewof the insert Fig. 7 is a plan view of the same.

' The apparatus may comprise a shaping machine A adapted to deliver bymeans of interchangeable mouth pieces, or through a mouthpiece whereofthe delivery may be adjustable, such as shown at a, in conjunction witha separating or severing device B, successive sections O of chocolate orother paste of predetermined dimensions; such sections being allowed todeposit upon sheets or leaves of tin-foil c, or other wrapping of.

appropriate size arranged in position for receiving the said sections ofpaste so that the driven by thegear' train a latter lie squarely on thewrapping in the position assigned therefor.

The severing device B may comprise a horizontally reciprocating cuttersuch as b operated by means of 'a lever b from a cam groove b formedin-a cam 6 fast on the shaft D. Brackets A are bolted or secured at 0 tothe table or support A of {the shaping machine A. The trunnions b of thecutter I) slide in horizontal grooves or slots (1* provided in thebrackets A", as shown in Fig. 1. This shaft D is driven from the firstmotion shaft E by means of chain, gearing e and differential or conedpulleys e e, the belt e of the latter being rendered adjustable by meansof the screw device 6 thus enabling the speed at which the machine isdriven to be varied. The shaping machine A is Themouthpiece a may befurnished with an insert a having sloping inner sides a and which isassed intoth'e mouthpiece a. 'The latter is ormed with guides I) so thata shutter or slide 0 may be inserted for securing the insert a inposition in said mouth piece a. Said slide or shutter c has aperforation coinciding with the orifice in the insert a The wrappin'gs cwhich form the under coveringfor the sweetmeat are preferably placed indefined positions by an attendant, upon an endless traveling platform ortable F the face of the latter being composed of transversely disposedslats of partially v-ulcanized rubber or other suitable material or of:material covered with rubber, springs being employed if desired togivethe desired elasticity The said-platform is firmly supported, sofas tooffer the desired resistance whether thesame be in motion orstationary.This platform or table is adapted to travelin such a manner as toremove, intermittently or ati suitably regulated intervals, the shapedand severed sections C of sweetmeat delivered from the aforesaidmouthpiece a, in order to make room for the next leaf of wrappingand-all ow of the deposition of another section of paste thereon, in theposition occupied by the previous one. Such intermittent travelingmovement of the platform F is effected by means of a ratchet f and pawlf operated by a rod f from an eccentricf on a transverse shaft DthisshaftD" being driven by bevel gearing d from the shaft D. The leaves ofwrapping c with the paste sections ect C thereon, latf orm F, of

By employing the hereinbefore described means of cooling the expensiverefrigerating appliances ordinarily employed may be dispensed with.

The cooled hardened and wrapped sweetmeat having passed from the chamberI,-

the mold is lifted off, there being no cohesion between it and thesurface of the Wrapping, the edges of the molded cake are trimmed so asto remove any superfluous wrapping, or paste, which may result from theaction of the stam s; the sweetmeat being then finished for t e market.

If no Wrapping of the paste is desired, the mold is placed with itsrecess directly upon the paste without the application of the up per orintervening wrapping leaf, and after cooling the contents are emptiedout.

What I claim and desire to secure by Letters Patent of the United Statesis:
